Abstract
The invention relates to a method for analyzing a multispectral image (), which includes designing a detection image from signal-to-noise ratio values. The signal-to-noise ratio values relate to the content of the multispectral image inside a window which is determined around each pixel, when the contrast in the window is maximized by a Fischer projection. The signal-to-noise ratio values at calculated from integral images of order one and two, which in turn are calculated only once initially, so that the total amount of calculations is reduced. The analysis method is compatible with a real-time implementation during a capture of consecutive multispectral images which form a video stream, in particular for an environment-monitoring task.
